I just opened my pool and had several questions around SWG. I installed it midway last season and had water pretty much in balance...I just tested and here's the results: TC:6.3 FC:5.8 pH:6.9 TA:40 CH:250 CYA/stabilizer:10
I know I had to keep my dial in my Goldline SWG real low at less that 10 to keep the chlorine at a usable level. Should I keep the CYA low as to maybe burn a little more Chlorine to keep it honest?
Also, I know it off topic, but I have some really nasty brown stains that appears organic since when I first opened they looked almost like debris. Now that a day or so went by (with plenty of shock), They seem to be just stains not debris. The "Pool Store" tried to sell me some stain remover crystals, but I didn't bite. Since this stain thing never happened to me in the past, it it related to SWG? Should've I closed the pool with different chemical balance?
